In this paper, we present a comprehensive overview on Ad hoc networking by directional antennas. Use of Directional antennas can largely reduce the interference, increase the spatial reuse and due to their longer range we can have routes with fewer hop for two distant nodes. However the main problem of using directional antennas in Ad hoc networks is due to the dynamic nature of the network. Neighbour discovery, maintenance the track of moving neighbours, exploitation of the benefit of long range and directional MAC protocols are the most challenging issues. We present three Directional MAC protocols and two combinational protocols and system which give solutions to MAC and Neighbour discovery and compare the throughput of them with 802.11 with omnidirectional antennas.

The widespread adoption of IEEE 802.11 WLANs is attributed to their inherent mobility, flexibility, and cost-effectiveness. Within the IEEE 802 working group, a dedicated task group is diligently advancing WLAN technologies, particularly tailored for dense network scenarios. Amidst these advancements, the 802.11ac protocols have emerged as a preferred choice, delivering superior data transfer rates compared to the preceding 802.11n standard. Significantly, the sixth-generation wireless protocol, IEEE 802.11ax, has been introduced, showcasing enhanced performance capabilities that outpace its fifth-generation predecessor, 802.11ac.In this pioneering investigation, we engage in an in-depth simulation-based scrutiny of prominentWLAN protocols—namely, IEEE 802.11n, IEEE 802.11ac, and the cutting-edge IEEE 802.11ax. Our exhaustive analyses traverse a spectrum of critical metrics, encompassing throughput, coverage, spectral efficiency, Tx/Rx gain, and Tx/Rx power.In a single-user and SISO scenario, both 802.11ac and 802.11ax outperform 802.11n. Significantly, 802.11ax surpasses the previous 802.11n/ac standards, highlighting substantial advancements in wireless performance.

Mobile Ad-hoc Networks (MANETS) consists of a collection of mobile nodes without having a central coordination. In MANET, node mobility and dynamic topology play an important role in the performance. MANET provide a solution for network connection at anywhere and at any time. The major features of MANET are quick set up, self organization and self maintenance. Routing is a major challenge in MANET due to it’s dynamic topology and high mobility. Several routing algorithms have been developed for routing. This paper studies the AODV protocol and how AODV is performed under multiple connections in the network. Several issues have been identified. The bandwidth is recognized as the prominent factor reducing the performance of the network. This paper gives an improvement of normal AODV for simultaneous multiple connections under the consideration of bandwidth of node.

Personal Communication Network (PCN) is an emerging wireless network that promises many new services for the telecommunication industry. The proliferation of demands for extending wireless services to integrated services, which supports the transmission of data and multimedia information, has resulted in the need for broadband wireless systems that are able to provide service capabilities similar to those of wire line networks. The ATM cell - relay paradigm is one possible approach to provide broadband wireless transmission with PCN’s using the ATM switching networks for interconnection of PCN cells. As traffic in these mobile cellular networks increases, Handoffs will become an increasingly important issue. As cell sizes shrink to accommodate an increasingly large demand of services, newer more efficient handoff schemes need to be used. In this paper, the authors describe the use of novel and efficient data structure which dynamically allocates guard channel for handoffs and introduces the concept of channel borrowing strategy. The proposed scheme allocates the guard channels for handoff requests dynamically, based on the traffic load for certain time period. A new originating call in the cell coverage area also uses these guard channels if they are unused. Our basic idea is to allow Guard channels to be shared between new calls and handoff calls. This approach maximizes the channel utilization. The simulation results prove that the channel borrowing scheme improves the overall throughput.

This article presents a probabilistic modeling method utilizing smart meter data and an innovative agentbased simulator for electric vehicles (EVs). The aim is to assess the effects of different cost-driven EV charging strategies on the power distribution network (PDN). We investigate the effects of a 40% EV adoption on three parts of Frederiksberg's low voltage distribution network (LVDN), a densely urbanized municipality in Denmark. Our findings indicate that cable and transformer overloading especially pose a challenge. However, the impact of EVs varies significantly between each LVDN area and charging scenario. Across scenarios and LVDNs, the share of cables facing congestion ranges between 5% and 60%. It is also revealed that time-of-use (ToU)-based and single-day cost-minimized charging could be beneficial for LVDNs with moderate EV adoption rates. In contrast, multiple-day optimization will likely lead to severe congestion, as such strategies concentrate demand on a single day that would otherwise be distributed over several days, thus raising concerns about how to prevent it. The broader implications of our research suggest that, despite initial worries primarily centered on congestion due to unregulated charging during peak hours, a transition to cost-based smart charging, propelled by an increasing awareness of time-dependent electricity prices, may lead to a significant rise in charging synchronization, bringing about undesirable consequences for the power distribution network (PDN).

In this paper, a multilayer perceptron guided key generation for encryption/decryption (MLPKG) has been proposed through recursive replacement using mutated character code generation for wireless communication of data/information. Multilayer perceptron transmitting systems at both ends accept an identical input vector, generate an output bit and the network are trained based on the output bit which is used to form a protected variable length secret-key. For each session, different hidden layer of multilayer neural network is selected randomly and weights or hidden units of this selected hidden layer help to form a secret session key. The plain text is encrypted using mutated character code table. Intermediate cipher text is yet again encrypted through recursive replacement technique to from next intermediate encrypted text which is again encrypted to form the final cipher text through chaining , cascaded xoring of multilayer perceptron generated session key. If size of the final block of intermediate cipher text is less than the size of the key then this block is kept unaltered. Receiver will use identical multilayer perceptron generated session key for performing deciphering process for getting the recursive replacement encrypted cipher text and then mutated character code table is used for decoding. Parametric tests have been done and results are compared in terms of Chi-Square test, response time in transmission with some existing classical techniques, which shows comparable results for the proposed technique.

In order to reduce the communication cost and time we are looking forward for successful implementation of an infrastructure less network like Mobile Ad Hoc Network in all arena of wireless mobile communication. But still it is a challenge to decide a most appropriate routing protocol for MANET. In MANET there is no fixed topology due to the mobility of nodes, interference, multipath propagation and path loss. Since MANET does not use fixed infrastructure rather it always have to find suitable router and routing path for each communication, existing established routing protocol is not suitable for MANET to function properly. Different Routing protocols have been proposed to meet the challenges with MANETs. This paper evaluates the performances of four MANET routing protocols which are DSDV, AODV, DSR and TORA over TCP, a Transport Layer Protocol. The performance metrics which are considered in this paper are packet delivery fractions, normalized routing overload, end to end delay and throughput. DSDV is a proactive protocol and the others are reactive protocols.

Secure communication between two nodes in a network depends on reliable key management systems that generate and distribute keys between communicating nodes and a secure routing protocol that establishes a route between them. But due to lack of central server and infrastructure in Mobile Ad hoc Networks (MANETs), this is major problem to manage the keys in the network. Dynamically changes in network’s topology causes weak trust relationship among the nodes in the network. . In MANETs a mobile node operates as not only end terminal but also as an intermediate router. Therefore, a multi-hop scenario occurs for communication in MANETs; where there may be one or more malicious nodes in between source and destination. A routing protocol is said to be secure that detects the detrimental effects of malicious node(s in the path from source to destination). In this paper, we proposed a key management scheme and a secure routing protocol that secures on demand routing protocol such as DSR and AODV. We assume that MANETs is divided into groups having a group leader in each group. Group leader has responsibility of key management in its group. Proposed key management scheme is a decentralized scheme that does not require any Trusted Third Party (TTP) for key management. In proposed key management system, both a new node and group leader authenticates each other mutually before joining the network. While proposed secure routing protocol allows both communicating parties as well as intermediate nodes to authenticate other nodes and maintains message integrity.

MANET (Mobile Ad-hoc Network) is hot spot for research due to its various advantages and disadvantages. Providing safe communication between mobile nodes, recognization the position of nodes, reducing overhead, handling misbehavior and location updates are such a difficult issues in ad-hoc network, so providing trust schemes is an important in this network. MANET provides some basic functions like routing, communication, network management and packet forwarding etc over self organized network. Because MANET has not a fixed topology, in which mobile nodes comes and leaves the network within a random period of time. It effects energy, bandwidth and memory computations of network. Providing trust in MANET is such a crucial task because it doesn’t having centralized infrastructure. In this paper, we survey the different trust model schemes of MANET with their unique features, merits and demerits & findings.

Ad-hoc networks are the collection of autonomous nodes where all the nodes are configured dynamically without any centralized management system. Mobile Adhoc Networks (MANETs) are self-configuring network of mobile routers connected via a wireless link. However,the feature of decentralization and dynamic configuration of nodes makes MANETs vulnerable to various security attacks,that are otherwise not so common in a wired network. For mitigation of these attacks,several secured routing protocols are being proposed till now. This paper provides the view of overall security breaches present in the Ad-hoc Networks till now and will discuss in brief about the several proposed secure routing protocols.

Position based routing plays a significant role in multi-hop Vehicular Ad hoc Networks (VANETs), due to high mobility of nodes. Selection of next-hop node is crucial to improve the performance of routing. In this paper, we have proposed a method for selecting next-hop forwarding node based on the distance between the source and next-hop node and link quality. Next-hop node is selected based on Expected Progress Distance (EPD) criteria. The EPD is estimated in terms of expected distance between the source and nexthop node. The expected delay (ED) and throughput (Th) are also estimated for the proposed method. The mathematical model derived for calculating EPD, delay, and throughput are simulated in MATLAB and evaluated the performance of the proposed method.

Mobile WiMAX or IEEE 802.16e gives the access of Broadband Wireless even when the station is moving. But, as always Wireless environment is more open to threats; various threats exist over Mobile WiMAX like “Downgrade Attack”, “Key Space Vulnerability” and “Initial Network Vulnerability”, and “Denial of Service (DoS)”. In this paper we are proposing solution for one of the main Threat which is Denial of Service attack. Proposed solution is based on Puzzle approach. As, of more critical environment of MobileWiMAX we have Proposed use of Time Stamp and Nonce Variable for providing the more secure environment prone to DoS. As, DoS mainly exist in two forms which have been mentioned further, proposed work in Literature provides the solution for either of these but our proposed solution will be an attempt to overcome from THE PHYSICAL INFRASTRUCTURE. WIRELESS NETWORKS REPRESENT AN IMPORTANT EXAMPLE OF SUCH SCENARIOS WHERE CAPTURING AND FORGING PACKETS ARE RELATIVELY EASY. ATTACKS AGAINST NETWORKED SYSTEMS ARE BECOMING MORE COMPLEX AND FOR MOBILE WIMAX IT IS MORE CRITICAL AS WELL AS MORE IMPORTANT TO HANDLE BECAUSE IT SUPPORTS SUBSCRIBER STATIONS MOVING AT VEHICULAR SPEEDS AND THEREBY SPECIFIES A SYSTEM FOR COMBINED FIXED AND MOBILE BROADBAND WIRELESS ACCESS.

Energy conservation has been an important area of interest in Wireless Sensor networks (WSNs). Medium Access Control (MAC) protocols play an important role in energy conservation. In this paper, we describe CSMA based MAC protocols for WSN and analyze the simulation results of these protocols. We implemented S-MAC, T-MAC, B-MAC, B-MAC+, X-MAC, DMAC and Wise-MAC in TOSSIM, a simulator which unlike other simulators simulates the same code running on real hardware. Previous surveys mainly focused on the classification of MAC protocols according to the techniques being used or problem dealt with and presented a theoretical evaluation of protocols. This paper presents the comparative study of CSMA based protocols for WSNs, showing which MAC protocol is suitable in a particular environment and supports the arguments with the simulation results. The comparative study can be used to find the best suited MAC protocol for wireless sensor networks in different environments.

In wireless network, fault tolerant topology control is an important and a challenging task. The wireless nodes and links could experience frequent failures since Wireless networks are usually deployed under extreme environments. Therefore, fault tolerance must be considered for many applications. In wireless network Topology control has been proved effective in saving node power. The main idea of topology control is that instead of using its maximal transmission power, each node sets its power to a certain level such that the global topology satisfies a certain constraint. To increase fault tolerance, nodes in the network will consume more power. Here we need to give the optimum distance between the nodes of the wireless network in order to reduce the consumption of the power of each node. This paper deals with the approach for the finding the minimum distance between the nodes of the wireless network by the use of mat lab coding through the graph theory considering the minimum weight based algorithm.

Orthogonal frequency division multiplexing (OFDM) is a widely used multicarrier modulation (MCM) technique in the field of wireless communications, specifically designed to facilitate high-speed data transmission. The use of several subcarriers inside an OFDM system for the transmission of modulated symbols results in the generation of OFDM signals with a significant peak-to-average power ratio (PAPR). In this study, we propose a novel approach for mitigating the high PAPR in wireless communication systems (WCS). Our method utilizes a partial transmit sequence (PTS) strategy, which is enhanced by using an adaptive particle swarm optimization (PSO) algorithm. In this study, we present a description of an OFDM system employing the standard PTS technique in conjunction with PSO. To mitigate computational complexity, the suggested methodology efficiently explores the optimal amalgamation of phase rotation components. Experimental findings demonstrate that the computational complexity and PAPR have been greatly minimized by the suggested method.

Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data among themselves without the reliance on a fixed base station or a wired backbone network and it the makes the routing a crucial issue to the design of the MANET. Multiple path routing protocols are shown to be performance-effective alternatives over single-path routing for ad hoc networks and it represents a promising routing method for wireless mobile ad hoc networks. Multi-path routing achieves load balancing and is more resilient to route failures..In this paper we propose an energy efficient multipath fault tolerant routing protocol to improve the reliability of data routing in Mobile ad hoc networks. The proposed RFTA is a multi objective routing protocol that meets diverse application requirements by considering the changing conditions of the network. The efficiency of the proposed protocol has been evaluated on different scenarios and there has been a noticeable improvement in the packet delivery ratio and also in the reduction of end-to-end delay comparing to SMR,SMS and MDSR.

QOS improvement has been a subject of intensive discussion. The research in the network field for congestion control is by means of scheduling packets from different traffic flows for processing at a specific node. When that particular node is selected for the transmission of all traffic flows since it has been chosen as an emerging node for the shortest path in the adaptive energy efficient algorithm, queue scheduling disciplines have been used to improve the quality of service. In this paper, we evaluate the performance of four queuing disciplines (FIFO, PQ, RED and WFQ) which is implemented in the AEERG protocol. This paper gives the NS-2 simulation results to compare their relative performance based on queuing delay, packet drop rate and end-to-end delay for the above queuing techniques.

The escalating demand for swift and dependable wireless internet access has spurred the development of various protocols within 802.11 WLANs. Among them, the 802.11ac protocols have gained widespread acceptance over the past few years, offering enhanced data transfer rates compared to the 802.11n standard. However, the persistent congestion of wireless IoT devices, particularly in densely populated areas, remains a significant challenge. To tackle this issue, IEEE 802.11 has advanced IEEE 802.11ax as the successor to 802.11ac, introducing critical enhancements at the PHY/MAC layers to improve throughput in dense scenarios. Additionally, modelling and simulating these protocols are vital for WLAN researchers and designers to anticipate link characteristics effectively, fostering high-performance WLAN design. The need for such tools led to the creation of diverse network simulation programs, and NS-2 is widely accepted as an open-source program that has achieved remarkable success in research. In this paper, we focus on various connection properties of 802.11ax WLANs through NS-3 simulations, including MCSs, bonded channels, GI, data encoding, antennas, data rates, link distance, Tx/Rx power, gain, and payload size. We also compare their performance against 802.11ac, which demonstrates that NS-3 accurately supports most 802.11ax capabilities and outperforms 802.11ac in various scenarios.

We explore different scenarios to explain the chemical difference found in the remarkable giant-giant binary system HD138202+CD−3012303. For the first time, we suggest how to distinguish these scenarios by taking advantage of the extensive convective envelopes of giant stars. Methods. We carried out a high-precision determination of stellar parameters and abundances by applying a full line-by-line differential analysis on GHOST high-resolution spectra. We used the FUNDPAR program with ATLAS12 model atmospheres and specific opacities calculated for an arbitrary composition through a doubly iterated method. Physical parameters were estimated with the isochrones package and evolutionary tracks were calculated via MIST models. Results. We found a significant chemical difference between the two stars (∆[Fe/H]∼0.08dex), which is largely unexpected considering the insensitivity of giant stars to planetary ingestion and diffusion effects. We tested the possibility of engulfment events by using several different combinations of stellar mass, ingested mass, metallicity of the engulfed object and different convective envelopes. However, the planetary ingestion scenario does not seem to explain the observed differences. For the first time, we distinguished the source of chemical differences using a giant-giant binary system. By ruling out other possible scenarios such as planet formation and evolutionary effects between the two stars, we suggest that primordial inhomogeneities might explain the observed differences. This remarkable result implies that the metallicity differences that were observed in at least some main-sequence binary systems might be related to primordial inhomogeneities rather than engulfment events. We also discuss the important implications of finding primordial inhomogeneities, which affect chemical tagging and other fields such as planet formation. We strongly encourage the use of giantgiant pairs. They are a relevant complement to main-sequence pairs for determining the origin of the observed chemical differences in multiple systems.

Mustard, as a crop, is susceptible to a variety of pests that can affect its growth and yield. Here’s a rundown of some common pests that target mustard plants: Aphids: These small, sap-sucking insects can cause significant damage by feeding on the leaves and stems. Aphids also excrete a sticky substance known as honeydew, which can lead to the growth of sooty mold on the plants. Flea Beetles: These tiny beetles jump like fleas when disturbed and chew small holes in the leaves. They are particularly damaging in the early growth stages of the plant. Cabbage Loopers: The larvae of a type of moth, these caterpillars are known for their distinctive looping movement. They chew large holes in the leaves and can defoliate plants if present in large numbers. Diamondback Moth Larvae: Another caterpillar pest, these larvae chew small holes in the leaves and can cause extensive damage, especially when infestations are heavy. Whiteflies: These are tiny, winged insects that feed on plant sap and can quickly become a problem in greenhouse or close planting conditions. Like aphids, they also secrete honeydew. Cutworms: These are the larvae of certain types of moths and are known for cutting young plants at the stem base at ground level. They are most destructive during the night. Root Maggots: The larvae of root maggot flies, these pests attack the roots of mustard plants, causing wilting and potentially killing young plants. Harlequin Bugs: These are colorful stink bugs that suck the sap from mustard plant stems and leaves, causing the leaves to become stippled, wilt, and eventually die if the infestation is severe. Mustard Sawfly: The larvae of the mustard sawfly can cause considerable defoliation, as they feed voraciously on the leaves. Clubroot: Caused by a fungus-like organism, clubroot affects the roots, causing them to swell and distort. While technically a disease, it is often associated with pest management because controlling it involves similar preventative strategies. Control Measures: Managing pests in mustard involves a combination of cultural, biological, and chemical methods. Crop rotation, resistant varieties, timely sowing, maintaining plant health, and using natural predators like ladybugs and parasitic wasps can help keep pest populations under control. Chemical pesticides should be used as a last resort due to their potential impact on the environment and non-target species.

Bollworms are among the most damaging pests in cotton cultivation, affecting the bolls where the cotton fibers are formed. There are several species of bollworms, each capable of causing significant yield loss and quality degradation if not effectively managed. Here’s a detailed look at the primary bollworm species affecting cotton: Cotton Bollworm (Helicoverpa armigera): Also known as the corn earworm or the Old World bollworm, this pest is found in many regions around the world. It is highly polyphagous (feeds on many different plants) and poses a threat not only to cotton but also to maize, tomatoes, and legumes. The larvae bore into the cotton bolls, feeding on the developing seeds and fibers, which can lead to boll rot. Pink Bollworm (Pectinophora gossypiella): A significant pest of cotton, the pink bollworm larvae infest the cotton bolls, feeding on the seeds and lint. This can severely damage or destroy the bolls. In regions where pink bollworms are prevalent, they have been a major driver for the adoption of genetically engineered Bt cotton, which expresses a bacterium gene toxic to certain insects. Tobacco Budworm (Heliothis virescens): Closely related to the cotton bollworm, the tobacco budworm primarily attacks tobacco but is also a common pest in cotton. It primarily damages the flowers and bolls of the cotton plant. Differentiating between the tobacco budworm and the cotton bollworm based on appearance can be challenging, but it is crucial for effective management. American Bollworm (Helicoverpa zea): Known in some regions as the corn earworm, it is similar in behavior to Helicoverpa armigera and poses a threat to a variety of crops, including cotton. The larvae attack the cotton bolls, leading to direct damage to the cotton lint and seeds. Management Strategies: Cultural Controls: Crop rotation, destruction of crop residues, and deep plowing can help break the pest’s life cycle. Timing of planting can also be adjusted to avoid peak pest infestation. Biological Controls: Natural enemies like Trichogramma wasps, which parasitize bollworm eggs, and predators such as lacewings and ladybugs can be encouraged. Bacillus thuringiensis (Bt) products can also be sprayed, which are particularly effective against young larvae. Chemical Controls: Insecticides may be required when infestation levels exceed economic thresholds. However, resistance management must be considered, alternating modes of action to avoid developing resistance. Genetic Approaches: Bt cotton, genetically modified to express Bacillus thuringiensis toxin, has been highly effective in controlling bollworms and has dramatically reduced the reliance on chemical insecticides. Monitoring and Scouting: Regular field scouting and using pheromone traps to monitor adult populations can help in timely and targeted application of control measures. The effective management of bollworms often requires an integrated approach

A botany file is similar to a chemistry practical file but specifically focuses on experiments and observations related to plants. It typically includes detailed descriptions of plant-related experiments, such as germination studies, growth experiments, tissue culture techniques, plant anatomy investigations, and ecological surveys. The file may contain records of plant specimens collected, their classification, characteristics, and ecological significance. Additionally, it may include diagrams, photographs, drawings, tables, and data analysis related to plant research. Like a chemistry practical file, a botany file serves as a documentation of practical work conducted in the field of botany and is often used for assessment and educational purposes.

Jupiter’s moon Io hosts extensive volcanism, driven by tidal heating. The isotopic composition of Io's inventory of volatile chemical elements, including sulfur and chlorine, reflects its outgassing and mass loss history, and thus records information about its evolution. We used millimeter observations of Io’s atmosphere to measure sulfur isotopes in gaseous SO2 and SO, and chlorine isotopes in gaseous NaCl and KCl. We find 34S/32S = 0.0595 ± 0.0038 (equivalent to δ34S = +347 ± 86‰), which is highly enriched compared to average Solar System values and indicates that Io has lost 94 to 99% of its available sulfur. Our measurement of 37Cl/35Cl = 0.403 ± 0.028 (δ37Cl = +263 ± 88‰) shows that chlorine is similarly enriched. These results indicate that Io has been volcanically active for most (or all) of its history, with potentially higher outgassing and mass-loss rates at earlier times.

Context. WASP-76 b has been a recurrent subject of study since the detection of a signature in high-resolution transit spectroscopy data indicating an asymmetry between the two limbs of the planet. The existence of this asymmetric signature has been confirmed by multiple studies, but its physical origin is still under debate. In addition, it contrasts with the absence of asymmetry reported in the infrared (IR) phase curve. Aims. We provide a more comprehensive dataset of WASP-76 b with the goal of drawing a complete view of the physical processes at work in this atmosphere. In particular, we attempt to reconcile visible high-resolution transit spectroscopy data and IR broadband phase curves. Methods. We gathered 3 phase curves, 20 occultations, and 6 transits for WASP-76 b in the visible with the CHEOPS space telescope. We also report the analysis of three unpublished sectors observed by the TESS space telescope (also in the visible), which represents 34 phase curves. Results. WASP-76 b displays an occultation of 260±11 and 152±10 ppm in TESS and CHEOPS bandpasses respectively. Depending on the composition assumed for the atmosphere and the data reduction used for the IR data, we derived geometric albedo estimates that range from 0.05 ± 0.023 to 0.146 ± 0.013 and from <0.13 to 0.189 ± 0.017 in the CHEOPS and TESS bandpasses, respectively. As expected from the IR phase curves, a low-order model of the phase curves does not yield any detectable asymmetry in the visible either. However, an empirical model allowing for sharper phase curve variations offers a hint of a flux excess before the occultation, with an amplitude of ∼40 ppm, an orbital offset of ∼−30◦ , and a width of ∼20◦ . We also constrained the orbital eccentricity of WASP-76 b to a value lower than 0.0067, with a 99.7% confidence level. This result contradicts earlier proposed scenarios aimed at explaining the asymmetry observed in high-resolution transit spectroscopy. Conclusions. In light of these findings, we hypothesise that WASP-76 b could have night-side clouds that extend predominantly towards its eastern limb. At this limb, the clouds would be associated with spherical droplets or spherically shaped aerosols of an unknown species, which would be responsible for a glory effect in the visible phase curves.

Understanding circumstellar disks is of prime importance in astrophysics, however, their birth process remains poorly constrained due to observational and numerical challenges. Recent numerical works have shown that the small-scale physics, often wrapped into a sub-grid model, play a crucial role in disk formation and evolution. This calls for a combined approach in which both the protostar and circumstellar disk are studied in concert. Aims. We aim to elucidate the small scale physics and constrain sub-grid parameters commonly chosen in the literature by resolving the star-disk interaction. Methods. We carry out a set of very high resolution 3D radiative-hydrodynamics simulations that self-consistently describe the collapse of a turbulent dense molecular cloud core to stellar densities. We study the birth of the protostar, the circumstellar disk, and its early evolution (< 6 yr after protostellar formation). Results. Following the second gravitational collapse, the nascent protostar quickly reaches breakup velocity and sheds its surface material, thus forming a hot (∼ 103 K), dense, and highly flared circumstellar disk. The protostar is embedded within the disk, such that material can flow without crossing any shock fronts. The circumstellar disk mass quickly exceeds that of the protostar, and its kinematics are dominated by self-gravity. Accretion onto the disk is highly anisotropic, and accretion onto the protostar mainly occurs through material that slides on the disk surface. The polar mass flux is negligible in comparison. The radiative behavior also displays a strong anisotropy, as the polar accretion shock is shown to be supercritical whereas its equatorial counterpart is subcritical. We also f ind a remarkable convergence of our results with respect to initial conditions. Conclusions. These results reveal the structure and kinematics in the smallest spatial scales relevant to protostellar and circumstellar disk evolution. They can be used to describe accretion onto regions commonly described by sub-grid models in simulations studying larger scale physics.
